In 1969 I went to Tipp City in Ohio to buy a whites metal detector, after buying it and going home I picked up my subscription of Coin World only to read that the bank in Tipp City released some one $ bill with mismatched serial no's. I check my change from buying the detector and sure enough there it was.......Tou might say this was my first find with my metal detector..............I still have the one $ bill..............Its worth a lot
